Description
TW 7450-42 sample changer is a complete laboratory automation system based on the TW 7450 basic unit fitted with sample rack TZ 3942 for 42 samples. The configuration includes titration head TZ 3963, rod stirrer TZ 1847 and 5 m FEP tubing, and operates on a universal 100-240 V supply. Designed for automated sample presentation in titration workflows, it enables efficient sequential processing of multiple specimens in analytical laboratories. The integrated rack and stirring assembly support consistent sample handling during potentiometric or volumetric determinations. This sample changer from manufacturer SI Analytics - a Xylem brand delivers a ready-to-use platform for high-throughput titration applications. With a net weight of 72 kg the robust unit is intended for permanent bench or system installation. It is particularly suited to quality-control and research environments that require reliable unattended sample changing, precise positioning and continuous stirring. The combination of dedicated titration head, rod stirrer and chemically resistant FEP tubing ensures compatibility with a wide range of aqueous and non-aqueous titrants while maintaining operational safety and reproducibility.

What is this article?
TW 7450-42, Sample changer TW 7450, basic unit TW 7450 with sample rack TZ 3942 is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand for laboratory use. It sits in pH & electrochemistry accessories, inside pH & electrochemistry, in Lab instruments.
These are the buffer-bottle holders, the electrode storage vials, the cables and the spare junctions. An electrode stored dry that should have been stored wet is a damaged electrode. The accessory has to be the one that electrode's manual names.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
